[PATCH v3 3/4] ARM: dts: dra72-evm-revc: add phy impedance settings

From: Mugunthan V N
Date: Thu Oct 06 2016 - 01:15:23 EST


The default impedance settings of the phy is not the optimal
value, due to this the second ethernet is not working. Fix it
with correct values which makes the second ethernet port to work.
